My house is a no outdoor shoe zone too. Nothing to do with cream carpets, dirt is dirt whether you can see it or not.
I never actually have to ask anybody to remove their shoes though, they see I'm in socks and automatically take off their shoes.
I do offer (clean) slippers to those who want them and will consider buying some if those plastic overshoes.
I think it's rude to expect to wear outdoor shoes in somebody else's home unless specifically invited to. Even then, Id rather remove mine.
Nearly a year on and not being able to speak to sister about our brothers passing
